Today I tried out the 2013 Tanner Hell Canopy goggles from Oakley they run about 170$. These utilize an oversized lens but will still fit most if not every helmet and with its low profile itís very easy to see all around without having to turn your head or tilt down so much. I wore them for about 3 hours straight with no problems, did not have to take them off for any reason or to adjust the fit. Dual layer Anti-fog lenses and dual vents help keep your vision nice and clear.
